boeing-viz/initial waypoints setup

[aleesteele]

My last PR, so bittersweet!

Here's a list of what it can currently do:

• The labels for pieces fade in and out as each paragraph scrolls up through the page, paragraph by paragraph.
• The counter increments with number of pieces & parts.

Missing features:

• Preview GIF to be used on post list (to be done once completed)
• The delayed fade in of pieces no longer functions. The setTimeout() feature was removed from this PR, so the pieces no longer fade in as needed.

Extra feature:

• Tucker had initial suggested a hover feature on the plane, that is initiated when the user clicks on the name of a part in a paragraph.

Bugs:

• Fade in may not occurring at the correct time now, after revising for the edits that Leeza suggested

@leezaweb Immense thank yous to Leeza for helping me to revise the logic of this; this wouldn't be what it is without her.

Re: The PR message above.. This may be solved by removing the offsets altogether or setting both to 50%, as this is the default for Waypoints: https://github.com/CSIS-iLab/trade_guys/pull/72/files#diff-ebb69480e554c54c6e49faf98f6d80dfR105
